: When the book provides multiple paths to the same answer, study each. This helps you recognize which methods (e.g., algebraic vs. geometric) are most efficient for specific problem types .
: Spend at least 2–3 days on a single difficult problem before checking the solution. The "joy of discovery" is essential for developing deep mathematical intuition . Mathematical Olympiads 2000-2001: Problems and ...
